RE: Using CheckLogin tag from within tiles

[Andrew Hill]

There is a small complication in that the users and roles often need to be
configurable from within the application by a user using the applications
UI.

ie: the users and roles (or to be more
precise:"role-group-like-things-wot-users-have") arent fixed and can be
changed during runtime. - The persistance of this info being handled by the
business layer rather than in the webApp - which doesnt have access to the
underlying database tables either.

Whats the 'best practice' for handling this sort of requirement (which I
imagine comes up a lot)?

To answer this question, you really need to think about what portion of
the problem is container-specific and what is not.  In the case of CMA,
the mechanism you use to set up users/groups/roles is container-specific,
but the application that you deploy is ***not*** container-specific.  Do
you see the difference?

All you need to do is configure users with the correct roles in both your
development environment and your production environment, and your app can
be appropriately tested, and then deployed with no changes to the WAR or
EAR itself.  That is because a WAR or EAR contains zero references to any
actual users - it only talks about roles and restrictions based on those
roles.  Authenticating users, and determining which roles they have, is
the container's problem -- not the application's problem.

Any application developer who thinks that he or she understands enough
about security (and all the possible things that can go wrong) to
implement application managed security safely is welcome to do so.  But
please warn me which publicly visible apps you've built, and I will make a
note not to use them.

I'm very serious about this.

If you don't have a fundamentally correct security implementation as an
overall top level goal (perfect security does not exist; it's all a matter
of how much you're willing to spend versus the risk/cost of security
breaches), you are wasting your time even bothering with it at all, unless
this is a trivially simple intranet app with no damaging implications if
your security scheme is bypassed by enterprising (or malicious) users.

Having been a Tomcat developer, I can tell you that even container managed
security cannot be trusted totally (despite how many hundreds of thousands
of times Tomcat has been downloaded, a long standing security
vulnerability was recently found (not with CMA in this case, but the
principle still applies).

But I will trust the container managed security implementation of any
widely deployed container a *lot* more than I will trust the application
managed security of any arbitrary application (including my own).  It is
very much worth the pain of having to be container-specific about
administering your user database to have some comfort in the fact that
better heads than yours has been involved in setting up your container's
authentication and authorization implementations.

You know the number one security-related question on TOMCAT-USER?  "How
can I authenicate my users using Windows security?"  Nobody even seems to
think about the security implications of sending usernames and passwords
across a network where people who are salivating to attack your server can
see it ...

Sheesh.

RE: Using CheckLogin tag from within tiles

[David Graham]

Craig,
I agree with most of your points but you must admit that the non-standard 
implementations of CMA are a pain.  Not really when you work for a company 
that sells a container (Sun, BEA, IBM) because you'll always be using 
their's, but when developing for a number of containers this can be painful.

It would help if at least one standard implementation was prescribed by the 
spec...I personally like tomcat's jdbc realm implementation.

Dave

My (exceedingly limited) understanding of CMA was that it was very container

One other thing to note about any non-CMA approach -- they don't help you
much (if at all) if you are accessing EJBs from your actions.  From the
point of view of the EJB container, all these requests will appear to be
from an unauthanticated user identity.  You can establish a 
identity in web.xml for these cases, but this applies to *all* EJB calls.

If you want the EJB layer to be able to make role-based access decisions
depending on who the logged in user is, you must use container managed
security.

Re: RedirectingActionForward?

[Eddie Bush]

I need to dig into the source more deeply.  I looked briefly but 
couldn't satisfy myself as to whether you could do a redirect that 
wasn't (at least) relative to the application.  Sorry, but this isn't an 
issue I've had to face.  As a last resort you could do:

response.sendRedirect(response.encodeUrl(path));
return null;

Returning null is very important, as it signals the RequestProcessor 
that it doesn't need to do anything else.

Hopefully someone else will have additional wisdom for you.

Problem reading ApplicationResources.properties..

[smaccutchan]

Hello all,

I am having some trouble with my struts application.. It doesn't seem to be
reading the ApplicationResources.properties file and when my Actions generate
errors all I get from the output of my  tag is "null null".

Here is a portion from my web.xml:


  action
  org.apache.struts.action.ActionServlet
  
application
EprojectsResources
  
  
config
/WEB-INF/struts-config.xml
  
  2


My EprojectsResources.properties file lives in
$TOMCAT_HOME/webapps/eprojects/WEB-INF/classes

My struts-config.xml:


  

  

  

 



 



  



(I ommitted the action mapping for listAllProjects.do to save typing, but it is
there)

The action that is returning the "null null" is the updateEngJob action..
Basically I can list the projects and edit them, but when I submit the form the
updateEngJob action returns the error "null null"

Some code from my UpdateEngJobAction.java class file:

import net.sinctech.eprojects.entity.EngJob;

public class UpdateEngJobAction extends Action {
  public ActionForward perform(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
  throws IOException, ServletException {

ActionErrors errors = new ActionErrors();

try {
  EngJobBO engJobBO = new EngJobBO();
  EngJob engJob = (EngJob)form;
  engJobBO.updateEngJob(engjob);

  return mapping.findForward("success");
} catch(Throwable e) {
  e.printStackTrace();
  ActionError error = new ActionError(e.getMessage());
  errors.add(ActionErrors.GLOBAL_ERROR, error);
}
saveErrors(request, errors);
return new ActionForward(mapping.getInput());
  }
}

my EngJobBO.updateEngJob(engJob):

Since you're using the nested tags, you'll have to figure out what names it gives the

ResolutionView object, which contains a Person, Address, etc.  I have this:



  

  


  

 
  

  



The only problem is that resView.getPreferredAddress() actually returns a
List, so the above bean:write tag produces something like: [123 State
Street, Phoenix AZ 12345] which is produced by the toString() method of the
List.

How do I work with the List instead of using bean:write?  I know how to do
it in Java, getting the iterator and iterating to get each value, which in
this case is a line of the address.  Do I need another logic:iterate tag?
(But the "bean" I need isn't in scope, it's inside the current resView
bean!).  An example would be appreciated-- I'm stuck.

Is this possible?

[Rea, Ron]

Hello, 
I'm not sure if this is possible from within a  tag, any
help would be greatly appreciated!
 
>From within my JSP, I am iterating through several rows of data and
displaying the data for modification.  One specific property is an
Explanation field.  What I'd like to do is create a "memo" link on each row
of data, and when that link is hit, a small page is displayed with only that
rows Explanation data.  The user enters up to 300 bytes of data for their
Explanation, within the pop-up, and when they close the pop-up, the specific
rows Explanation property is updated within the  section.   
 
I can create the pop-up, but after I enter the data, the rows Explanation
property is not updated.  Any ideas?  Is this possible?
 
Thanks!
 
Example of code:
 
JSP:

 

Approve
Deny



' ,'');" onMouseOver="window.status='Click to enter an Override
Explanation...';return true;" onMouseOut="window.status='';return
true;">memo

  
  
 
Javascript:

function getText(name, output, msg, dataValue, msgKey) {
newwin = window.open('','','top=150,left=150,width=325,height=330');
if (!newwin.opener) newwin.opener = self;
with (newwin.document)
{
open();
write('');
write('
' + msg +
'
');
write('
Message Code: ' + msgKey + '');
write('
' + dataValue + '');
write('
');
write('
');
close();
   }
}

RE: Using Frameset within Struts - displayed a blank page

[Tuan H. Le]

Hi Brian,

Thanks for your response! I tried to define a forward within the /selectTab action, 
but I still see a blank page. The new action mapping is below





Read the Struts archive, it seems that using tiles/template is a better choice than 
calling in action in the frame src attribute.

Also, it would be much appreciated if some one can share a sample code and 
configuration on how to develop tabs functionality with frame and tiles. I'm going 
through tiles-documentation tutorial. 

The layout that we have for our application is below

Top frame: Tab labels
Middle frame: content body
Bottom frame: other data and footer.

Thanks!
Tuan

Interesting.  Never tried calling in action in a SRC attribute.  Seems like it works 
since you are getting a blank page, and not a HTTP: 404 error ( Page not found ).

When I see blank white pages it is usually a problem with your forwards.  I don't see 
a forward defined in the selectTab action definition in the Struts-config file.
Is it a Global forward? is it misspelled in your code?  

Keeping in mind that the input attribute doesn't get checked for forwards, that is 
used for validation.

Instead of using the page attribute why not use the HREF attribute.  

This should work more to you liking.

Used the taglib a bit at my last gig, never noticed the behavior you're describing.  
One thing to note:  The Collection the taglib sorts is stored in the session.  Did

RedirectingActionForward?

[Angie Lin]

Hi there,

RedirectingActionForward doesn't seem to redirect anymore.  It's trying 
to forward and I'm ending up with a garbled URL like:

http://localhost:7001/myapp/http://someothersite.com/

My code is:
ActionForward oldfwd=mapping.findForward("othersite");
String path=oldfwd.getPath();
path.append("?id="+id);
RedirectingActionForward newfwd=new RedirectingActionForward(path);
return newfwd;


This used to work in 1.0.2, but I've since upgraded to 1.1b.   I'm also 
using WL6.1 if that helps at all.  

I've searched the archive and read the thread on message 38728, but that 
problem was fixed by setting the contextRelative attribute to true, 
which doesn't quite help me, since I'm trying to forward to another 
domain.  

Any other configuration settings I might be missing?

One other thing to note about any non-CMA approach -- they don't help you
much (if at all) if you are accessing EJBs from your actions.  From the
point of view of the EJB container, all these requests will appear to be
from an unauthanticated user identity.  You can establish a 
identity in web.xml for these cases, but this applies to *all* EJB calls.

If you want the EJB layer to be able to make role-based access decisions
depending on who the logged in user is, you must use container managed
security.

RE: Declarative Exception handling with Struts 1.1-b2

[Taylor, Jason]

what about extending your existing Exception classes?  You could make your
existing ones interfaces or abstract classes that are used by the as is
software, and the extending classes are there more or less just to indicate
differences to the declarative exception handler.  That way, you can use
Struts 1.1b2 right-out-of-the-box and you benefit from forward compatibility
with later releases of 1.1.  I think it's always nicer to use polymorphism
than special flags, etc.  Make sense?

Yea, you can't use the same exception class for 
different exception elements. The RequestProcessor looks 
up the exception element to use based on the exception  
type. You would need to have different exceptions 
specified in the "type" attribute for each exception 
element.

Here's a thought. Extend the RequestProcessor and 
override the processException() method. The exception 
object is one of the arguments in the method. Use the 
exception to get your specific exception code.

Then create your own ExceptionHandler that uses the 
exception code to lookup the proper key and creates the 
ActionError and stores it. 

So, you might have to extend 2 classes, but it should be 
very little work to do this and modify the behavior.

Someone else may have a better idea, but this shouldn't 
be that bad. Again, the only reason the framework can't 
do this for you is because you have the same exception 
class for different exception types.

Re: Using CheckLogin tag from within tiles

[Eddie Bush]

Oh - one more thing.  Filters really are a lot more flexible in that 
they can be deployed with the application.  I've heard of instances 
where hosting providers wouldn't configure realms for folks (nor would 
they do anything else that required a server config change) - and that 
is where a Filter would become an absolute necessity!

Security Chapter from O'Reilly Struts Book

[chuckcavaness]

As many of you know, I had to cut several chapters from 
the book due to time and size. Unfortunately, the 
chapter on security is one of those that got cut. I've 
received many email messages asking me if I was going to 
include it in the next edition or write it later. I've 
decided to write it and just make it freely available on 
the Struts site (assuming I can get one of the 
committers to post it). 

I'm going to put an outline together this week. If you 
would like to drop me any topics that you would 
especially like to see covered, I'll include them in the 
outline. I'll write the chapter, all you have to do is 
tell me what extra topics you want to see.

I'll post a draft outline within a week and get some 
feedback and then start writing it. As with the other 
comments and suggestions, please don't clog the Struts 
user list. Just send your comments and/or suggestions to 
[EMAIL PROTECTED] I'll respond accordingly.

Chuck,

I have already tried that but I wonder if it works. In my case struts-config
looks like below.  

   
 

 

Now whenever java.myexception.GenericException is thrown, the message
corresponding to last entry is getting displayed, i.e., message corresponding
to "template.id.null" key. Please correct me if I am wrong.

Ah, I see the confusion. The Struts framework will use 
the value from the "key" attribute in the exception 
element to automatically build ActionErrors for you. You 
just need to use the  tag to display them.

To see where in the framework all of this takes place, 
check out the source code for the ExceptionHandler class.

Hope this helps,

Re: Using CheckLogin tag from within tiles

[Eddie Bush]

The only "implementation differences" would be in the way you configure 
it.  The use of it (from within your application) is governed by the 
spec, so there's not a lot of "wiggle room".  The configuration, 
however, is not governed by the spec ... so how it is setup will 
certainly vary from container to container :-(

I always use Tomcat, so it isn't an issue to me.  A buddy stuck on iAS 
3.5 was visiting with me about their approach and I suggested CMA to him 
(over implementing it in *every* servlet! ... no, they had no 
"utilitarian" functions they were calling - they were actually 
reimplementing it).  Turns out on iAS 3.5 there's a servlet you can 
configure for this.  In Tomcat, I just setup a JDBCRealm (there are 
other Realm implementations) and I'm done - piece of cake.

I've never used CMA because of potential implementation differences across

Re: Using CheckLogin tag from within tiles

[Eddie Bush]

... or use container-managed authentication (CMA) :-) and place the 
burden on the server itself.  Sorry - had to chip in!  I honestly don't 
know how long CMA has been a part of the servlet specification - but I'd 
wager that wouldn't be spec 2.3 dependent ;-)

Re: Using CheckLogin tag from within tiles

Another of those best practices is to use a Filter to authenticate the user 
before they ever reach your application.  This requires a servlet 2.3 
compliant container and doesn't easily allow you to use struts specific 
classes.

So, if you don't need struts to authenticate and are using a 2.3 container, 
use the Filter approach.

Re: How to change struts log level in Tomcat 4.1.x?

[Eddie Bush]

Keith :-) Please don't continuously repost the same exact question. It
doesn't benefit anyone. If you don't get a reply, it's probably because
the post hasn't come across the eyes of someone that knows - or someone
that is confident enough about their knowledge to share it. Reposting is
a really good way to get your posts totally ignored :-) and I don't
think you want that (I personally find it very annoying - we get enough
traffic as it is).

Have you seen my reply to this question? Did it help? Have you tried
anything yet? Many Jakarta projects are using commons-logging nowadays -
you might breeze by commons and check for information on
commons-logging. Log4J is a popular logger - conveniently you can also
find information about it on the Jakarta site. If you're under JDK1.4
I'd recommend searching Sun's site for help configuring JDK the 1.4 logger.

Remember: This is a volunteer effort, and many of us have other, more
pressing, things we have to do than just sit here and respond to your
inquiries as quickly as we can.

Re: Using CheckLogin tag from within tiles

[James Mitchell]

There have been many "best practices" published (media) and posted (users
list) over the last year or so that, if followed, can/would elimiate these
kinds of issues.

By forcing all interactions with your webapp to go through your custom
actions, you can keep your "check for session expire" code in your action
classes and not have to rely on your jsp to enforce it.

I typically do this in an abstract BaseAction which all actions (except
those not requiring authentication or session data) are required to extend.

By placing my "is session expired" code in the base action, I do not have to
replicate the check anywhere else, which elimiates this issue.

Not sure why this is happening, but see above for avoiding it as well.

RE: Declarative Exception handling with Struts 1.1-b2

[chuckcavaness]

Ah, I see the confusion. The Struts framework will use 
the value from the "key" attribute in the exception 
element to automatically build ActionErrors for you. You 
just need to use the  tag to display them.

To see where in the framework all of this takes place, 
check out the source code for the ExceptionHandler class.

Hope this helps,

How to change struts log level in Tomcat 4.1.x?

[Keith Cheng]

Hi all,

As far as I know, the default log level of struts is INFO, how can I 
change it to other level such as DEBUG? I am using struts 1.1b2 with 
Tomcat 4.1.10.

Thanks!

Regards,

Re: How to change struts log level when using it with Tomcat 4.1. x?

[Eddie Bush]

 guess again ;-) Nowadays, since commons logging is used, that
setting in web.xml is for backward compatability - and I don't think it
does *anything*.

I gather you're trying to get some more detail? Seems to me you may be
able to create "commons-logging.properties" in your top-level classes
directory, and specify something like:
org.apache.struts=DEBUG

I haven't attempted to configure just commons logging though. If you're
either using Log4J or you're under JDK1.4 (and using the JDK 1.4
logger), you can mention the package (you can get as fine-grained as to
specify a given class) in a different logging config file
(log4j.properties for log4j and ... you probably don't want to use the
default one under JDK1.4 - hit Sun's site to see how to use a different
file).

Of course, you could always take the "easy" way out and just hack the
source ;-) (if you think learning to configure logging is too big a
pain!) but I'd figure out how to control it with your logging properties
- it's a lot fast/easier/dependable ;-)

RE: Declarative Exception handling with Struts 1.1-b2

[Harvinder Singh]

Thanks Chuck,

Actually we are porting existing code and hence there are pre defined set of
Exception classes and we have decided not to add any more exception classes.
We are using error code to identify the exact problem.

I agreed that I can define path variables for all the keys to "error.jsp",
like

   

 



But how do I fetch corresponding error message in my "error.jsp" file. Don't
I need to hardcode the "key" in the "error.jsp" like below. If not, please
point out how do I do it.

<%@ page language="java" %>

I may be misunderstanding your situation completely. If 
I have, I apologize ahead of time. Here's the short 
version of what I think.

Can you not throw more specific exceptions, ones that 
imply a little more about what went wrong? Then setup 
exception elements in the global section (or in the 
Action mappings if they are specific to the Action) and 
configure the application resource key for that specific 
exception.

I'm sure you understand this, but let me emphasize 
anyway, the point of declarative exception handling is 
that you shouldn't have to do anything programmatically 
to display errors. You specify what the error page is 
using the "path" attribute in the exception element. In 
your case, since you want all errors to go to the same 
page, the path attribute would be "error.jsp" for all of 
your exception elements. 

Does that make sense? Again, let me know if I 
misunderstood the question completely.

Re: NullPointerException in TabsLayout??

[Cedric Dumoulin]

  Hi all,

  I have found what is wrong: tomcat 4.1.12 do reuse of the tag 
, and one property of the tag was not used properly. I 
have now corrected the implementation class of the tag 
(UseAttributeTag.java): the tiles tabs example now works with Tomcat 
4.1.12. The modification will be available in next nightly build.

RE: Declarative Exception handling with Struts 1.1-b2

[chuckcavaness]

I may be misunderstanding your situation completely. If 
I have, I apologize ahead of time. Here's the short 
version of what I think.

Can you not throw more specific exceptions, ones that 
imply a little more about what went wrong? Then setup 
exception elements in the global section (or in the 
Action mappings if they are specific to the Action) and 
configure the application resource key for that specific 
exception.

I'm sure you understand this, but let me emphasize 
anyway, the point of declarative exception handling is 
that you shouldn't have to do anything programmatically 
to display errors. You specify what the error page is 
using the "path" attribute in the exception element. In 
your case, since you want all errors to go to the same 
page, the path attribute would be "error.jsp" for all of 
your exception elements. 

Does that make sense? Again, let me know if I 
misunderstood the question completely.

Hi all,

As far as I know, the default log level of struts is INFO, how can I 
change it to other level such as DEBUG? I am using struts 1.1b2 with 
Tomcat 4.1.10.

RE: connection pools

adolfo,

take a look at commons-dbcp for database pooling 

http://jakarta.apache.org/commons/dbcp.html

and commons-pool for generic pooling

http://jakarta.apache.org/commons/pool.html

Good luck!  You can direct any questions you have about using it to the commons-user

Does Apache provides any more complete pool? Any nicer pool anywhere?

Try commons-dbcp from Jakarta.
http://jakarta.apache.org/commons/dbcp.html

It is integrated with several products (tomcat, hibernate)
and works nicely.

RE: Passing a request parameter within Struts framework

[Tuan H. Le]

Hi Luca,

Great suggestion! Also, I agree with you about not using frame, but we have a business 
requirement that requires us to use a frame, ie: the user does not want to see the 
table headings (and some other data) disappear in a page when they scroll down the 
list of records.

Thanks,
Tuan

Subject: Re: Passing a request parameter within Struts framework


Hi,
your problem is clear, and it has very few solutions :)
The problem is that you use frames. Every Frame in a different request,
then the request from your form..end at the page containing the 
frameset, and your request with your parameters set in your form ends 
here. All the pages inside the frames are different GET requests from 
the browser, then they cannot have access your parameters and 
attributess (belonging to you former request).
Solutions:
if your parameter is only a string you can build a string chain..in the 
src of your frame tag:
" 
name="top" id="top" frameborder="0" scrolling="no" noresize 
marginwidth="0" marginheight="0" framespacing="0">
In this case your new request wll have the parameter named myparameterName.
It's very unelegant solution but it could work
Second put your object in the user's session. it's resonable to put it 
in session after all, if I understand well, is an attribute of a user's 
profile.

A general suggestions, don't user frames in dynamic pages, you can have 
always problems with them, Jsp has a nice templating machanism, use that 
to build your header or footer.

RE: Passing a request parameter within Struts framework

[Thomas Eichberger]

Hmmm, try to read out all request parameters, request attributes, and 
session attributes in the start of the page.

Something like

for ( Enumeration enum = request.getAttributeNames(); enum.hasMoreElements(); )
{
 Object key = enum.nextElement();
 Object value = request.getAttribute( key );
 System.out.println( key + " --> " + value );
}

to find out more...


Put that code in a utility method (maybe there is one in the struts library???)

RE: Form bean is null in pagecontext? - OK let's try this again...

[Kevin Roast]

Title: Message



OK, ignore my 
witterings :-) Since the object is in request scope it must be accessed 
thus:
 
BaseForm form = (BaseForm)pageContext.getAttribute(Constants.BEAN_KEY, 
pageContext.REQUEST_SCOPE);
 
This 
works fine.
 
My confusion 
stemmed from the fact that getAttribute() returns null when an item doesn't 
exist as opposed to throwing an error.

  Hi,
   
  OK, it appears 
  that I'm using the wrong key here - i.e. I should be using BEAN_KEY to 
  get the Form bean not the form tag (doh).
   
  HOWEVER - this 
  doesn't explain why the ALL of the attributes on the request scope are "null" 
  e.g. I've printed them out to the console:
   
  org.apache.struts.taglib.html.FORM=nulldataForm=nullorg.apache.struts.taglib.html.BEAN=null
   
  I've looked at 
  the Struts code that sets the attributes in FormTag.doStartTag() and it 
  looks ok:
   
      // Store 
  this tag itself as a page

Hi, 
Does anyone know, at what point does the form 
bean get added to the pageContext as an attribute? (with the key 
org.apache.struts.taglib.html.Constants.FORM_KEY) 
The reason I ask, is that I have a custom tag 
that needs to access the form bean class directly (I have created a base 
form bean class with methods I require), and I'm trying to do something like 
this in the tag code:
BaseForm form = 
(BaseForm)pageContext.getAttribute(Constants.FORM_KEY); 
Where "BaseForm" is my form bean base class 
type. 
However this returns null. Any ideas? The form 
is specified as "request" scope in the config file. 
Thanks, 
Kev

Re: Passing a request parameter within Struts framework

[Luca Zago]

Hi,
your problem is clear, and it has very few solutions :)
The problem is that you use frames. Every Frame in a different request,
then the request from your form..end at the page containing the 
frameset, and your request with your parameters set in your form ends 
here. All the pages inside the frames are different GET requests from 
the browser, then they cannot have access your parameters and 
attributess (belonging to you former request).
Solutions:
if your parameter is only a string you can build a string chain..in the 
src of your frame tag:
" 
name="top" id="top" frameborder="0" scrolling="no" noresize 
marginwidth="0" marginheight="0" framespacing="0">
In this case your new request wll have the parameter named myparameterName.
It's very unelegant solution but it could work
Second put your object in the user's session. it's resonable to put it 
in session after all, if I understand well, is an attribute of a user's 
profile.

A general suggestions, don't user frames in dynamic pages, you can have 
always problems with them, Jsp has a nice templating machanism, use that 
to build your header or footer.

RE: Passing a request parameter within Struts framework

[Tuan H. Le]

Hi,

I added Andrew's code tip as below, but it still returns a null value for the request 
parameter.

public final class LoginAction extends Action {
  public ActionForward perform(  ) {
// . . .
ActionForward curForward = mapping.findForward( target );
String path = URLUtil.addParameterToURL( curForward.getPath(), "selTopNav", "1" );
System.out.println( path );
ActionForward newForward = new ActionForward( path, curForward.getRedirect() );
return newForward;
  }
}

public class URLUtil {
  public static String addParameterToURL( String anURL,
  String aParameter,
  String aValue ) {
if ( anURL == null ) {
  return aParameter + "=" + aValue;
} else {
  return anURL + ( (anURL.indexOf( "?" ) == -1) ? "?" : "&" ) + aParameter + "=" + 
aValue;
}
  }
}

-- MainMenu.jsp (where it get forwarded to for a successful login -
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>



















 Top.jsp (a frame within a frameset and where the request.getParameter get called) 
--

Selected Top Nav: <%= request.getParameter( "selTopNav" ) %>


This returns a null value instead of "1".

I must have missed some thing here.

Thanks,
Tuan

Had another look at your question and realised it is attributes rather than
parameters (Im always getting these mixed up!) that you stated in your
original question! (hehe guess my response was too quick!).
Given that this is the case, it should be useable in the next page unless
the forward is a redirecting forward.
Dont use jsp much so cant remember the 'best' way to expose it to the page,
but you could probably use a runtime expression thinghy (<%=
request.getAttribute("selTopNav"); %>

If however you need it as a request parameter the way I always do it is as
mentioned below and heres some code to illustrate:

firstly a simple method for adding parameters onto urls:
(btw: you can probably lose the first half of that "if" - Im just paranoid
about nulls ;->)

public static String addParameterToURL(String url, String parameter, String
value)
{
  if(url == null)
  {
return parameter + "=" + value;
  }
  else
  {
return url + ( (url.indexOf("?")==-1) ? "?" : "&" ) + parameter + "=" +
value;
  }
}

and to use this with forwards:

ActionForward fwd = mapping.findForward( target );
String path = addParameterToURL(forward.getPath(),"selTopNav","1");
ActionForward newFwd = new ActionForward(path,fwd.getRedirect() );
return newFwd;

Andrew,

Thanks for a quick response! Do you have a sample code that I can use? It
seems to me that are several lines of code to complete your suggestion. Is
this the only way to pass a request parameter within the LoginAction to
another JSP page? Eventually, I need to pass the request parameter selTopNav
(the user's selected tab) value back and forth to determine which tab the
user has selected.

Thanks again!

In your action you can create a new forward object and return that.
ie: get the forward for target, extract its url and append required
parameter(s) and create a new forward using that and the redirect value from
the one you looked up, and return the new one.

[OT] Multinested exceptions class

[Frederic Laub]

Hi,

Sorry for polluting this newsgroup with this Java question on Exception
handling,
but I didn't succeed to implement the multi-nested exceptions class of
chapter 10
 of the Jakarta Struts Book Review:
http://www.theserverside.com/resources/strutsreview.jsp
and I thought I could borrow a few seconds from some Java Guru.

I have a main method that calls sequentially method A and than method B.
Method A and method B are throwing databaseException.
In the main method I want to process method B even if an exception is thrown
by method A.
The main method will throw an exception if errors occurred in method A
and/or method B,
the exception thrown by the main method will contain a collection of
exceptions.
I suppose the main method is a good candidate for this type of exception
handling?
In the main method:
 try {
  call method A
  } catch (DatabaseException e) {
   // LoadException extends BaseException which
   // has a Collection attribute, (among others) a method for adding an
exception
   // and one for retrieving the whole collections.
   LoadException loadException = new LoadException();
   loadException.addException(e);
   }
 try {
  call method B
  } catch (DatabaseException e) {
Question:  How do I add this DataBaseException to the previously created
loadException in method A?
   }
Question: Where do I put the code to read the collection of exceptions if
any?

An example or a link to a multi-nested exception example would be great!

Thank you for your time.
Frederic

This is how i am using the  tag for all my links invoking

As u can see there is no use of "target" attribute

Funny part is that for all my links it opens a new window, if i keep the new
window open, all the links then open in this new window
That means i always have 2 windows open if i click on a link.
Is there some browser setting i need to check, i use IE5.5  and Netscape 6.2

Subject: RE: Passing a request parameter within Struts framework


Had another look at your question and realised it is attributes rather than
parameters (Im always getting these mixed up!) that you stated in your
original question! (hehe guess my response was too quick!).
Given that this is the case, it should be useable in the next page unless
the forward is a redirecting forward.
Dont use jsp much so cant remember the 'best' way to expose it to the page,
but you could probably use a runtime expression thinghy (<%=
request.getAttribute("selTopNav"); %>

If however you need it as a request parameter the way I always do it is as
mentioned below and heres some code to illustrate:

firstly a simple method for adding parameters onto urls:
(btw: you can probably lose the first half of that "if" - Im just paranoid
about nulls ;->)

public static String addParameterToURL(String url, String parameter, String
value)
{
  if(url == null)
  {
return parameter + "=" + value;
  }
  else
  {
return url + ( (url.indexOf("?")==-1) ? "?" : "&" ) + parameter + "=" +
value;
  }
}

and to use this with forwards:

ActionForward fwd = mapping.findForward( target );
String path = addParameterToURL(forward.getPath(),"selTopNav","1");
ActionForward newFwd = new ActionForward(path,fwd.getRedirect() );
return newFwd;

Andrew,

Thanks for a quick response! Do you have a sample code that I can use? It
seems to me that are several lines of code to complete your suggestion. Is
this the only way to pass a request parameter within the LoginAction to
another JSP page? Eventually, I need to pass the request parameter selTopNav
(the user's selected tab) value back and forth to determine which tab the
user has selected.

Thanks again!

In your action you can create a new forward object and return that.
ie: get the forward for target, extract its url and append required
parameter(s) and create a new forward using that and the redirect value from
the one you looked up, and return the new one.

Re: question

[deepank]

Hi,

This is how i am using the  tag for all my links invoking
different actions

[Form Review Team]
As u can see there is no use of "target" attribute

Funny part is that for all my links it opens a new window, if i keep the new
window open, all the links then open in this new window
That means i always have 2 windows open if i click on a link.
Is there some browser setting i need to check, i use IE5.5  and Netscape 6.2

Wierd. Is it just for your struts app, or does any link in your browser do
this (ie: some dodgy browser setting).
If the former, take a look at what you have specified for your target
attribute (if in doubt check the generated html of your page to see what is
really output to browser). If that window/frame does not exist the browser
will open a new one.

I'm sure it does not by default.

Check out attributes of your  tag and attributes of generated 
HTML tag. There may be also some  in your HTML document.

RE: Order or multivalued paramter

[Andrew Hill]

I believe so (at least Im relying on it in my apps!) at least under IE5 and
NS6/Mozilla it seems to.
(I havent seen a spec document stating it, but I havent looked either!).


Interestingly if you use client side DOM manipulation to reorder those
fields on the page, in IE they will submit in the new order, but in NS they
will still submit in the old order. :-(

RE: Same Action Class, same form, more submits

[Andrew Hill]

Take a look at the DispatchAction. This does the same thing you are but
saves you some typing.

The reason why you get null in the second case is that for the html:image
tag the browser doesnt submit the value when clicked but rather submits the
x and y position of the mouse when the image was clicked using the
parameters bob.x and bob.y (where bob=whatever you specified for property).
(This isnt struts fault, but rather the brilliant way way html was defiend
to work).

This makes it a damn nuisance working out which image was clicked (short of
resorting to JavaScript to set a hidden field in the images onclick or
append a parameter to the form action). Using html:submit of course works
the way one wants it to, which is why your code works.

Hi,
I noticed in devoloping with struts a design problem, probably because I
don't know well the framework :)
I mean that the main risk with struts is devoloping a lot of action
classes for every micro functionality.
For example I often have a form, and in this form two submits
which must call different functions on the same data submitted by the
form. I would like to have the same action class for all the operations
I can perform on the same submitted data.
If my submits are:




I can distinguish between the sumit seleceted by the user, with a
control on the request parameter "action" inside the Action class and
then excute different operations according to the user submit choice.
But this is a tricky, not a nice pattern, first the value is the same
string showed on the page.. second if I use a




this doesn't work anymore..because the request "action" parameter is null.
Has somebody an idea to solve this problem? Or is there in struts a
better design pattern to face this problem?

Thank in advance to all,

Passing a request parameter within Struts framework

[Tuan H. Le]

Hi,

How do I pass a request attribute to another form? In my case, after a successful 
login, it would forward the user to 
the main form (MainMeu.jsp which has a frameset). In the main form, it has several 
tabs. By default, it displays the
first tab.

Currently, in the perform() method of LoginAction class, I have the following code

//...
request.setAttribute( "selTopNav", "1" );
return( mapping.findForward( target ) );


Here's the code for the MainMenu.jsp


<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>




















And, in the Top.jsp, I have a test code to get a value of the request attribute, but 
it always returns a null value

Top Nav: <%= request.getParameter( "selTopNav" ) %>

Here's a partial of my struts-config.xml file

  


  

  

  

  
  











  


Do you know what I'm missing?

which must call different functions on the same data submitted by the 
form. I would like to have the same action class for all the operations 
I can perform on the same submitted data.
If my submits are:




I can distinguish between the sumit seleceted by the user, with a 
control on the request parameter "action" inside the Action class and 
then excute different operations according to the user submit choice.
But this is a tricky, not a nice pattern, first the value is the same 
string showed on the page.. second if I use a




this doesn't work anymore..because the request "action" parameter is null.
Has somebody an idea to solve this problem? Or is there in struts a 
better design pattern to face this problem?

Thank in advance to all,
Luca

I don't think so. Try to explain why do you think
you need different form beans for that.

Declarative Exception handling with Struts 1.1-b2

[Harvinder Singh]

Hi,
Can anybody help me in understanding declarative exception handling with
Struts1.1b2? My requirement is maintaining only single "error.jsp" file,
which should be displayed when an exception is thrown. We are having multiple
exception classes and when an exception is thrown an error id is associated
with it to get appropriate message. If I put all the error code vs error
messages in ApplicationResources.properties, there should be a way to fetch
the error code from the thrown exception, and then displaying the appropriate
message. Any help is appriciated.
Thanks,
Harvinder

RE: Form bean is null in pagecontext? - OK let's try this again...

[Kevin Roast]

Title: Message



Hi,
 
OK, it appears that 
I'm using the wrong key here - i.e. I should be using BEAN_KEY to get the 
Form bean not the form tag (doh).
 
HOWEVER - this 
doesn't explain why the ALL of the attributes on the request scope are "null" 
e.g. I've printed them out to the console:
 
org.apache.struts.taglib.html.FORM=nulldataForm=nullorg.apache.struts.taglib.html.BEAN=null
 
I've looked at the 
Struts code that sets the attributes in FormTag.doStartTag() and it looks 
ok:
 
    // Store 
this tag itself as a page 
attribute    
pageContext.setAttribute(Constants.FORM_KEY, this, 
PageContext.REQUEST_SCOPE);
 
Any ideas what's 
going on here?
 
Cheers,
 
Kev

Is this happening during the population of the form bean (which Struts
does for you)?  Do the exception messages show up only in the debug
messages, and not cause problems in your application itself?

If the answer to both questions is "yes", then this is harmless.  The
BeanUtils.populate() method operates like this:
- Iterate over the keys in the Map that is passed in (i.e. over
  the names of all request parameters included in the request)
- If there is a matching property on the destination bean,
  do the appropriate set
- If there is no matching property on the destination bean,
  ignore this request parameter

The exception is being triggered by the getPropertyDescriptor() call used
to test the third condition.

RE: O'Reilly struts book

I know this might be cheeky, but would it be possible to post the chapters

I'm reviewing the final PDF version of the book right 
now and will be done with that in a week. It should be 
heading for the printer right after that and be out very 
soon.

Since several chapters had to be cut for size, the Table 
of contents was slightly reorganized and renumbered. 
Every chapter except one (chapter 8) was posted that 
will be included with the book. The TOC that is shown on 
theserverside review site 
(http://www.theserverside.com/resources/strutsreview.jsp)
 is correct. Of those chapters, only the custom tag 
chapter was never posted. This was because I was re-
writing it right up until my deadline.

Look through the available chapters by name, don't worry 
about the chapter number. That has been adjusted in the 
final version. But just so you won't be disappointed, 
the TOC on that page is correct. Several chapters 
(unfortunately like security) had to be axed to keep the 
book at a respectable size.

Q: Validator - query properties

[gernot . pfingstl]

If a html input field is required I use the validator plugin and put 
...depends="required"... in my validation.xml file. This works great!
In the jsp pages I mark required fields with a "*", until now I
hardcode the "*" in my jsps, so if I change a field to required I had
to put the "*" in the jsp and to change the validation.xml.
My intend is to write a jsp tag, which parses the validation.xml
and put the "*" automatically, if the filed is required.

e.g. 

Had I to parse the validation.xml manually or is there a api
call to query validation properties? Due to the fact that dependencies could
depend on the locale, it would be nice to have a api and not to parse it
manually.

Thanks, Gernot

Re: html:form focus causes a javascript error if the element is aradio button

[Gilles . Vandaele]

Hi sweet archangel of the list,

Having had a look at those bugs (12248 and 1586 ) it seems that the problem
is that javascript is uncorrectly generated for an indexed field.
Does it mean that we have to know before the generation if the field is an
indexed one? eg. do we need to add the [0] in the tag attribute for a radio
button?
My problem is that I don't know (at creating the JSP), what kind of input
field the focus will have to be set on.
I thought that the focus attribute had to be set as 'The field name to
which initial focus will be assigned with a JavaScript function.'
(struts-documentation 1.0.2). They don't talk about any index!

Hi,
 I am not sure about this, but i have had this problem. Make sure your bean
follows the specifications of a Bean.
All properties have getter/setter methods. Sometimes Struts(or reflection i
should say)  will not recognize your class as bean because if this.
Also double check if your storing it in some scope in your Action class.

RE: Cannot find bean error

[Victor CHEVALIER]

javax.servlet.ServletException: Cannot find bean EMTTaskDetail in scope null

This doesn't mean your scope is not valid but that there is no bean in the
scope you specified. So if you specified no scope, this mean there is no
bean in 'memory'.
Verify the tag  (logic taglib definition).

On another side, if you iterate through an array of specified Objects, you
must provide a type in the iterate tag.

Hi,

I am trying to loop through an ArrayList returnd by a bean inside


Name in the Iterator tag specifies a bean set in request scope in my
ActionBean, getter on which will return an ArrayList. I am trying to read
the bean returned by the ArrayList inside the Iterator tag. There is an
exception thrown:

javax.servlet.ServletException: Cannot find bean EMTTaskDetail in scope
null

I tried specifying all the possible scopes, session and request but it still
throw this exception

The scriptlet looks something like this:



  

 ...

getTaskDetails() on the bean set in the request scope with key
"timesheetDetails" returns an ArrayList of EMTTaskDetail objects.

Thanks for your help.
